Pangolins (穿山甲), the world’s only mammals with scales (鳞片), have existed on earth for about 60 million years. Pangolins are very sensitive creatures and most of them don’t like staying indoors. In the wild, they’re slow to reproduce and give birth to only one baby at a time. Pangolins are alone and shy — nearly impossible for even the most devoted field researchers to catch sight of.

However, over recent ten years, their wild population has decreased greatly. More than a million pangolins are believed to have been taken from the wild in Asia and Africa. In the first eight days of April 2019 alone, authorities caught two 14-ton shipments of pangolin scales in Singapore, representing about 72,000 animals and worth a combined $90 million. In February, Malaysian seized a 33-ton shipment of mostly whole, frozen pangolins.

“The present scale of trade could drive this species to extinction,” said an Indian official.

If the illegal pangolin trade continues at such high levels, it’s thought that another 10 years might see them die out altogether. The trade is caused by a series of factors, but the fact that the local government doesn’t make strict laws against it plays a major role.

Another big challenge facing pangolins is that so few people know what they are and why they’re in such danger. As National Geographic Photo Ark photographer Joel Sartore says, “You won’t save what you don’t love.”

1.According to Paragraph 1, pangolins ______.

A.are rare mammals B.like living indoors

C.are outgoing but sensitive D.are easily found in the wild

2.What is the main reason for pangolins’ trade?

A.People in Africa like hunting pangolins.

B.Strict laws against it haven’t been made.

C.Pangolins’ population is increasing rapidly.

D.Pangolins have existed on earth for a long time.

3.What is the Indian official’s attitude towards the scales of trade?

A.Uncaring. B.Puzzled.

C.Supportive. D.Worried.

4.What is the main idea of the text?

A.Pangolins are hunted in Asia.

B.Pangolins are facing extinction.

C.People are trying to save Pangolins out of love.

D.Many countries are taking action to protect Pangolins.

The African elephant,the largest land animal remaining on earth ,is of great importance to African ecosystem(生态系统).Unlike other animals,the African elephant is to a great degree the builder of its environment.As a big plant-eater,it largely shapes the forest-and-savanna(大草原)surroundings in which it lives,therefore setting the terms of existence for millions of other animals that live in its habitat(栖息地).

It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat.In its continuous search for the 300 pounds of plants it must have every day,it kills small trees and underbushes,and pulls branches off big trees.This results in many open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas.In these open spaces are many plants in various stages of growth that attract a variety of other plant-eaters.

Take the rain forests for example.In their natural state,the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.By pulling down trees and eating plants,elephants make open spaces,allowing new plants to grow on the forest floor.In such situations,the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.

What worries scientists now is that the African elephant has become an endangered species.If the elephant disappears,scientists say,many other animals will also disappear from large areas of forest and savanna,greatly changing and worsening the whole ecosystem.

1.What is the passage mainly about?

A. Disappearance of African elephants.

B. Forests and savannas as habitats for African elephants.

C. The effect of African elephants' search for food.

D. The eating habit of African elephants.

2.What does the underlined phrase “setting the terms” most probably mean?

A. Fixing the time.                  B. Worsening the state.

C. Improving the quality.             D. Deciding the conditions.

3.What do we know about the open spaces in the passage?

A. They result from the destruction of rain forests.

B. They provide food mainly for African elephants.

C. They are home to many endangered animals.

D. They are attractive to plant-eating animals of different kinds.

4. The passage is developed mainly by________..

A. showing the effect and then explaining the causes

B. pointing out similarities and differences

C. describing the changes in space order

D. giving examples

Elephants on the coast of Thailand are acting strangely. They stamp their feet and signal toward the hills. The sea draws back from the beaches. Fish fall heavily in the mud. Suddenly, a huge wave appears. This is no ordinary wave. It is a tsunami (海啸)!

Tsunami waves are larger and faster than normal surface waves. A tsunami wave can travel as fast as a jet plane and can be as tall as a ten-story building. Imagine dropping a stone into a pond. The water on the surface ripples (起涟漪). A tsunami is like a very powerful ripple. Tsunamis begin when the ocean rises or falls very suddenly. Large amounts of seawater are displaced. This movement causes huge waves.

If a tsunami happens, there must be some kind of force that causes the ocean water to become displaced. Most tsunamis are caused by underwater earthquakes. However, volcanoes, landslides (塌方), large icebergs, and even meteorites (陨石) are able to cause one of these giant waves.

Tsunamis are extremely powerful. Ordinary waves lose power when they break. Tsunami waves can remain powerful for several days. Because tsunami waves are so strong, they can kill people, damage property, and completely ruin an ecosystem in just one hour.

Scientists have no way of predicting when a tsunami will hit. However, if a powerful enough earthquake happens, scientists can send out a warning or a watch. A warning means that a tsunami will very likely hit soon. A watch means that conditions are favorable for a tsunami. When people are informed of a watch or a warning, they have more time to prepare. It is best not to get caught unaware when a tsunami is on the way!

1.Why are elephants acting strangely before the Tsunamis?

A.They dislike the huge wave.

B.They are afraid of the big fish.

C.They can sense something out of the ordinary.

D.They see the ocean drawing back from the beaches.

2.What does the underlined word “displaced” in paragraph 2 mean?

A.Moved out of normal place. B.Pushed by human force.

C.Pulled to great heights. D.Hung down quickly.

3.Why do Tsunamis cause so much destruction?

A.They are not familiar to most people.

B.They are very powerful and long-lasting.

C.They break on the coast, unlike normal waves.

D.They are caused by underwater earthquakes.

4.What is this text mainly about?

A.How to guard against tsunamis. B.Differences between wave types.

C.What to do with tsunami waves. D.Causes and effects of tsunamis.
